Description

GENUS AND SPECIES OF PLANT CLAIMED

Lantana sp.

VARIETY DENOMINATION

‘Chapel Hill Gold’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana sp., and hereinafter referred to by the cultivar name ‘Chapel Hill Gold’.

The new Lantana plant originated as a branch mutation on Lantana sp. ‘Chapel Hill Yellow’ (Plant patent application Ser. No. 11/999,902, filed Dec. 7, 2007, now allowed). The cultivar ‘Chapel Hill Gold’ originated and was discovered in a cultivated environment at Watkinsville, Ga.

Asexual reproduction of the new cultivar by stem cuttings in Watkinsville, Ga. has shown that all the unique features of this new Lantana, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘Chapel Hill Gold’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Chapel Hill Gold’. These characteristics in combination distinguish ‘Chapel Hill Gold’ as a new and distinct cultivar: 1. Low growing, layered and spreading growth habit; 2. Leathery, scabrous dark green foliage; 3. Continuous flowering; 4. Bright golden yellow flower buds and flowers; and 5. Cold hardiness to USDA Hardiness Zone 7.

Plants of the new Lantana ‘Chapel Hill Gold’ differ from plants of the parent, ‘Chapel Hill Yellow’, primarily in flower color, as plants of ‘Chapel Hill Yellow’ have pale yellow flower buds that open to medium yellow with a darker yellow-orange center.

Plants of the new Lantana can be compared to plants of the cultivar ‘New Gold’. However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of the new Lantana differed from plants of the cultivar ‘New Gold’ in the following characteristics: 1. Plants of the new Lantana had darker green, thicker, more scabrous foliage than plants of the cultivar ‘New Gold’; 2. Plants of the new Lantana had brighter golden yellow flower buds and flowers than plants of the cultivar ‘New Gold’; and 3. Plants of the new Lantana were consistently cold hardy from year to year, whereas plants of the cultivar ‘New Gold’ lacked consistent cold hardiness.
